C[Correct. This point is critical to both sides' territorial frameworks];

C[After White defends, Black pushes again.];
W[dh];B[ie]
LB[aj:A]
C[And now Black can jump here to solidify the moyo and support the 2 stones to the left.
Note that Black still can slide to A to reduce White's territory even further.]

C[White caps from one direction, so ...];

C[... Black runs in the other direction.];
W[ff]
C[White can keep pushing from the outside.];
B[de];W[dd]
C[Now Black will have to scrounge for two eyes. Even if Black lives, White's outside strength will become even greater. White's outside strength is already casting a shadow on Black's framework on the right.]

C[Black's strategy might work here, if Black could now enclose the entire lower center area. But the area is open at both A and B.]
